The Amethyst Vintage uses a dual diaphragm capsule and is designed for that classic warm sound from the best vintage microphones. Large size diaphragms are made of the highest quality 6-micron Mylar film. Using Violet Design original technology the diaphragms are tensioned and adjusted on precisely made brass backplates. The diaphragms are sputtered with the Violet Design special formula gold mixture. It gives them faster impulse transient response without sound coloration or low frequency reduction, and adds the ability to handle louder sound pressure levels. At the end of the manufacturing process each capsule is carefully checked for all parameters and measured in an anechoic chamber for optimum of performance.

The unidirectional cardioid polar pattern reduces ambient studio noise. It has minimal proximity effect and is linear over the wide frontal incidence angle. The microphones headgrill is made as acoustic filter of multilayer brass mesh that reduces plosive sounds, breath, pop and wind noises, minimizes internal resonance effects, but keeps high frequencies and sound transparency.

The internal solid state preamplifier of the microphone is based on class-A fully discrete transformerless electronics circuit, built using only the highest quality selected components. The circuit is designed under the highest audio standards and provides linear audio frequency range, high dynamics, low self-noise, and very low audio distortion of all types. The Amethyst requires quality and stable 48V phantom power.

The Amethyst is ready for direct mounting on the standard microphone stand. Rugged microphone construction and two internal shockmounts, separately for the capsule and for the electronics, effectively reduces stand rumble, outside infrasonic interference and mechanical shocks. The additional external elastic studio shockmount is available as option.

APPLICATIONS:

The Amethyst microphone is designed for recording studio all-around needs, capable of capturing vocals, piano, guitars, drums, percussion, strings, wind and other instruments. The microphone can be successfully used in professional sound reinforcement systems, in broadcast and TV studios, in movie and video industry, project studios and home recording, and many other applications.
